Characterizing Hydrologic and Geomorphic Processes in a Spring-Fed, Cold-Desert Headwater Stream

The role of natural versus human-influenced factors in sedimentation of Littlefield Creek, a small, high-desert creek in south-central Wyoming is currently unknown. In general, there is little empirical information about both hydrologic and geomorphic processes (together described as hydrogeomorphic) in these types of streams.  To develop a better understanding of  hydrogeomorphic processes,...

EcoFlows: Understanding Streamflow Dynamics in Small Mountain Streams

The WY-MT WSC is collaborating with the Northern Rocky Mountain Science Center to understand the dynamics of streamflows in small, mountain streams during the course of the year, and to describe the amount of variability associated with those measurments. These findings will assist fisheries biologists who are researching temperature and streamflow effects on cutthroat trout and will help...

Wyoming Landscape Conservation Initiative: Water Resources

The Wyoming Landscape Conservation Initiative is a long-term science-based effort to assess and enhance aquatic and terrestrial habitats at a landscape scale in southwest Wyoming, while facilitating responsible development through local collaboration and partnerships. The WLCI is an interagency working group of partners that is beginning the process of establishing a much larger coalition of...

WLCI: Groundwater Streamgages in the upper Green River Basin

Real-time groundwater streamgages are created at existing streamgages by adding streambank wells (piezometers) to expand the understanding of groundwater/surface-water interaction. The object of this project is to:

  • Identify interactions between the stream and near-surface groundwater
  • Evaluate data to determine annual patterns and changes over time

Smith River Watershed Investigations

The Smith River watershed is an important recreational and agricultural area in Meagher and Cascade counties in west-central Montana. Thousands of visitors travel to the area annually to float and fish the Smith River. Additionally, most of the water used to irrigate 36,000 acres of the upper Smith River watershed is withdrawn from the Smith River or its tributaries. During a...

Living on the Edge: Predicting Effects of Climate Change on Native Fishes in Northern Great Plains Streams

Organisms that live in the semi-arid prairies in the Northern Great Plains are able to live through conditions of extreme heat, cold, floods, and drought. The fish that inhabit the warm, turbid waters of northern Great Plains streams are indicators of change in these delicate ecosystems, where water quantity and water quality are often precariously close to ecological tolerance limits. In fact...

Development of Regional Curves Relating Bankfull-Channel Geometry and Discharge to Drainage Area for Hydrophysiographic Regions in Wyoming

The Watershed Program in cooperation with the U.S. Geological Survey (USGS), Wyoming Water Science Center developed regional curves that relate bankfull channel dimensions and discharge to drainage area for hydrophysiographic regions in Wyoming where data are currently lacking. Regional curves are useful aids for estimating bankfull discharge and related channel dimensions at ungaged sites,...

Montana Crest-Stage Gage Network

The purpose of the crest-stage gage network is to inventory and monitor peak discharges throughout the state of Montana, with special emphasis on streams that may damage transportation infrastructure. Recorded data documenting peak streamflow at various sites within the state will be used by the Montana Department of Transportation to support assessments of culvert size, bridge construction,...

Probability of Streamflow Permanence (PROSPER)

PRObability of Streamflow PERmanence (PROSPER)

Rivers and streams are constantly changing. Streamflows can change throughout the year and between years due to snowmelt, precipitation, diversions, and return flows. For many streams, these fluctuations determine whether a stream has year-round flow or not. PROSPER is a project initiated to better understand what causes these fluctuations...
